O grupo Streptococcus anginosus é composto por bactérias habitualmente indolentes e comensais, pouco envolvidas em processos patológicos em pessoas saudáveis, mas podendo atuar como agentes oportunistas em doentes com comorbilidades graves, associados sobretudo a abcessos. Apresenta-se o caso de um doente de 63 anos do sexo masculino com múltiplas comorbilidades, incluindo diabetes mellitus, internado por insuf...
Wilson disease (WD) is a genetic disorder of copper metabolism caused by mutations in the ATP7B gene resulting in toxic copper accumulation in several organs. WD can manifest as liver disease, a progressive neurological disorder, a psychiatric illness, or a combination of these. Other clinical manifestations can also occur. Diagnosis is challenging and typically requires a range of biochemical tests, imaging, g...
Drug induced liver injury (DILI) is a condition with a wide clinical spectrum. The diagnosis represents a challenge not only due to the large number of known hepatotoxic products but especially when the substance involved is not known to induce liver damage. Empagliflozin is linked to several adverse effects but has not been convincingly associated to DILI. We report a case of a 70-year-old type 2 diabetic woma...
Drug-induced liver injury is hardly diagnosed, considering not only the wide range of hepatotoxic substances but also the diversity of associated phenotypes and the absence of specific biomarkers. Symptom chronology, drug or toxic exposure, and temporal association help to establish the diagnosis. Exposure to isopropanol has known but rare toxic effects. We report the clinical case of a 33-year-old female haird...
Background: The current standard of treatment in primary biliary cholangitis (PBC) is ursodeoxycholic acid (UDCA), although a considerable proportion of patients show incomplete response resulting in disease progression. Objective: This study aimed to assess the prevalence of incomplete response to UDCA and determine associated patients' characteristics. Methods: Patients with PBC as main diagnosis were include...
Introduction: Immunoglobulin light chain-associated amyloidosis results from extracellular tissue deposition of fibrilforming monoclonal immunoglobulin light chains, secreted by a clone of plasma cells. Although the liver is often involved histologically, most cases are clinically asymptomatic, and severe intrahepatic cholestasis as the primary manifestation of the disease is rare. Clinical Case: We report an u...
A tuberculose miliar é a forma de doença progressiva resultante da disseminação hematogénea maciça do Mycobacterium tuberculosis (MT). Afecta imunodeprimidos e idosos e tem manifestações clínicas insidiosas e inespecíficas. O caso clínico descrito refere -se a um homem adulto, sem imunodeficiência, com infecção simultânea por Coxiella burnetti e MT. A raridade desta associação e a sua forma de apresentação subl...
Em Medicina Interna, somos muitas vezes confrontados com o diagnóstico de doença maligna avançada, em doentes que desconheciam sofrer de patologia tumoral. A localização do tumor primitivo é fundamental, pois dela depende o correcto tratamento do doente. Alguns casos, e apesar de uma investigação exaustiva, permanecem sem diagnóstico, mesmo quando já ocorreu metastização. A Tomografia de Emissão de Positrões (P...
Introdução: A hepatite auto-imune (HAI) é uma inflamação hepática de causa desconhecida, caracterizada pela presença de hepatite de interface na biopsia hepática, de hipergamaglobulinemia e de auto-anticorpos característicos. Objectivo: Avaliar as características clínicas, laboratoriais e histológicas, a resposta à terapêutica e o prognóstico da hepatite auto-imune. Métodos: Análise dos processos clínicos dos d...
Introduction: Autoimmune Hepatitis (AIH) is a hepatocellular inflammation of unknown cause, characterised by the presence of interface hepatitis on liver biopsy, and hypergammaglobulinaemia and autoantibodies in serum.Objective: To characterise clinical, laboratory and histological features, as well as the outcome, of AIH.Methods - Retrospective analysis of AIH cases admitted between 1987 and 2002 in an Interna...
